UNITED STATES PATENT OFFICE.

ROBERT M. DOWNIE, OF BUTLER COUNTY, PENNSYLVANIA.

WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 228,737, dated June 15, 1880.

Application filed May 13, 1880.

To all whom it may concern Be it known that I, ROBERT M. DOWNIE, of the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Well Drilling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in well-drilling machines; and it consists in the use of a spring-pole in the place of the usual heavy walking-beam, and in the operating parts combined therewith, whereby a simple, light, and cheap machine is produced, which can be readily transported from place to place.

The machines for well-drilling heretofore in use are mostly of an unwieldy construction, occupying a large space and working but slowly, owing to the walking-beam by which the motion is communicated to the drill-tools.

In this improvement I discard the walkinging-beam and use the spring-pole, the velocity and extent of the action of which may be increased or diminished as desired. By dispensin g with the walking-beam a great weight is removed that greatly cucumbers well-drilling machines and prevents them from being made portable.

In my improvement all parts are made light, and one man controls the action of the machine without leaving his-place.

Figure l is a plan view of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view, partly in section.

A represents a suitable rectangular frame, having secured to it at one end the post K. Fastened upon the top of this post is a springoperating rod, a. At any suitable distance from the post K is a second post, j, upon the top of which the spring pole or rod rests.

In the front end of the frame A are placed suitable bearings B, in the top edges of which is journaled the reel f, the shaft of which reel has a large friction-wheel, 0, upon one end. This friction-wheel has bearing against it a suitable brake, g, which is operated by the hand-lever 12. By bearing against this wheel 0 by means of the brake g the speed at which (No model.)

the rope connected to the tools'used in the digging of the well shall be drawn from or wound upon the reel can be regulated at will.

In front of the reel f is another smaller reel, 6, which carries the sand-pump rope. One end of this smaller reel is journaled in the sliding box L, which is operated by means of the lever 0. On the end of this reel is a small friction-wheel, n, which can be moved in or out of contact with the flange Q, formed on the inner rim of the large driving-wheel R.. When-this small wheel is in contact with the interior of the rim or flange of this large driviugwheel the reel is operated for the purpose of drawing up the sand-pump; but when the wheel is moved out of contact with the rim or flange the weight of the sand-pump will cause the rope to unwind.

Upon the opposite end of the shaft to which the large driving-wheel is secured is a crank or wheel, S, provided with a wrist-pin, which is connected to the spring-pole a, by a suitablerod, T. To the upper end of this springpole is connected the rope for the operating drill-rod. As the large wheel is made to revolve by means of the driving-engine, which is placed inside of the frame A, the motion is communicated to this wheel, and from the wheel S the motion is communicated to the spring-rod in such a way as to operate the drillrod upand down.

By the use of a spring-rod, instead of the usual heavy walking-beam, not only is the weight of the walking-beam dispensed with, and the machine made to run more rapidly, but the elastic force of the pole is made to help to raise the drill-rod on its upstroke.

The ropes from the two reels pass over suitable pulleys, which are supported in the 1' ram egork over the top of the wheel, as shown in The operator stands in front of the machine, within reach of the two levers.

The machine is set in motion by means of the belt which connects it with the steamengine.

Having thus described my invention, I claim 1. In a well-drilling machine, the combination of the reel f, brake g, and lever 19 with the wheels 0, R, and S, substantially as shown.

2. In a well-drilling machine, the combinahave hereunto set my hand this 29th day of tion of the reel f, wheel 0, brake g, and lever April, 1880.
